San Fernando has taken disciplinary action against an assistant coach after Granada Hills alleged the coach took out a cellphone and was shooting video at a Granada Hills practice session, according to City Section Commissioner John Aguirre.

The incident took place a day before the schools were scheduled to scrimmage last week. Granada Hills canceled the scrimmage and sent to San Fernando internal video to support the allegation, according to Aguirre.

Assistant principal Jeremy Lawrence said the coach has been suspended for one game.
